This articleArticleDescribes how to process gesture events in multi-touch web development.Gesture in fruit devices, broadly speaking, includes click, flick, double-click, and scale) rotate and so on. IOS has designed a series of gestures to simulate and extend mouse operations. For example, a click event is triggered when a finger is put down, the mouse slides up and stops, and the onscroll event of the body is triggered. However, the narrow gesture e

Today we will count the number of handy gestures that Apple has integrated into the iOS7. They're not necessarily a function of changing the world, but they're changing the way we use the IOS habit. "Back" everywhere. It's a bit exaggerated everywhere, but this return gesture does run through system setup and native applications, and third-party apps are starting to integrate the gesture. Push off the background You can push up three points

Iefans tells you not to just exercise one hand's muscles, would you mind thinking about the other hand? We have previously introduced the desktop version of IE10 shortcut keys, but now like to use the Metro version of the IE10 more and more people. If you are also using this version, you might as well take a look at the Metro version of the IE10 commonly used shortcuts, and of course, faster than the shortcut button mouse gesture operation. If you are using a touch-controlled tablet device, rem

1. Introduction Some bloggers read the previous blogIOS interface-drawer interaction on the left side of Netease newsIn Weibo, I asked how to drag and drop content and comments in NetEase news, How to embed uinavigation above. Many people may have such a demand. Now it takes some time to make these two effects, Share with you. The idea is similar to the previous article, but uinavigation is not used. In my opinion, The comment button can be added through addsubview. The interaction between conte

C ++ 11 code display: Simple Gesture Recognition and response, up-down left and right, 11 gestures This is the code of the parkfun game, so it follows the normal logic to the left to the right. sliding up and down is supposed to perform the jump operation. The current scenario is static, so the logic is not pulling the camera before and after moving. The lambda function implementation of C ++ 11 is used to compare operations in STL. Although I know t

Use canvas to create a tree that can swing with gestures Create a swinging tree as the background of the page as needed. In order to increase page interaction, I added a mouse (touch) event to the tree in the background so that he could make corresponding actions based on the mouse (touch, the tree will swing as your fingers slide up or down or left or right. First, let's look at the final effect.Step 1. Complete the HTML page and create a new tree cl

Because recently developed projects involve HTML5 development on mobile devices, which requires a carousel effect. Then the quickest way, you know (Bootstrap), then the native Bootstrap carousel.js plugin does not support gestures.And then...... Find your own way, and then, there are 3 solutions:JQuery Mobile (http://jquerymobile.com/download/)$ ("#carousel-generic"). Swipeleft (function() { $ (this). Carousel (' Next');}); $ ( "#carousel-generic"). Swiperight (function() { $ (this). Carousel

1 Preface Gestures are actually a combination of touch events. gesture event recognition must be added to a uiview class. Multiple gesture identifiers can be added to a single view. Once some gesture actions are captured on this interface, this view will pass the gesture action to other gesture identifiers.Some touch events require support from the mobile phone system. The following are six gesture identifiers provided by IOS sdk5.• Swipe // stroke•

If you are using the storyboard layout, and the use of the system's return button, it will automatically have a sliding back effect, but I believe you do the project, is generally used by the custom return button, so I paste a few lines of code to see how to implement the system comes with the sliding back.First, create a custom return button, and then add the [self.navigationItem setLeftBarButtonItem:backBarItem];And then- (void) Viewwilldisappear: (BOOL) Animated {[Super viewwilldisappear:ani

Returns: True if the event is consumed, else false General meaning:E1 represents an event that is triggered by the moment the finger is pressed,E2 represents an event triggered when the finger is not bouncing and movingThe remaining two parameters roughly mean the number of pixels per second moving in the X, y direction.So, by E1 and E2, you can create a judging condition for gestures.Simple left and right swipe gesture code:@Overridepublic boolean onfling (
